1.8V/3.3V Switchable GPIO in TSMC 28nm
A TSMC 28nm Wirebond I/O Library with a switchable 1.8V/3.3V GPIO, with Specialized RF Wirebond Cells for LNAs.
Overview
A TSMC 28nm Wirebond I/O Library with a switchable 1.8V/3.3V GPIO, with Specialized RF Wirebond Cells for LNAs.
A key attribute of this silicon-proven, inline library is to detect and adjust to a VDDIO supply of 1.8V or 3.3V during system operation. The GPIO can be configured as input, output, open-source, or open-drain with an optional 60kohm pull-up or pull-down resistor. Digital cells for 25MHz, 75MHz, and 150MHz allow optimization across SSO currents & power. Cells for I/O, core power & ground with built-in ESD circuitry are included. The library meets 2kV HBM, 500V CDM, and 2kV IEC 61000-4-2 standards.
